VENDING-MACHINE.

Specification of Letters Patent.

Patented May 9, 1916.

To HH Hwm it muy concern Be it known that I. (luxuries F. RiemannsoN, a citizen of the United States, and a resident of the city of lwoonsocket, in the county of Providence, State of Rhode Island. have invented new and useful Improvements in Vending-Machines, of which the following is a specification.

This invention relates broadly to check controlled apparatus and more specifically to coin controlled vending machines of. the manually operated type.

The principal object ot this invention is to construct a manually operated vending machine wherein hoth the delivery and the coin controlled mechanisms are positively actuated to release the locking' mechanism and to deliver a package.

It is also a primary object of this invention to construct a manually operated vending: machine in such manner that the parts will withstand excessive use and abuse without the possibility of deranging the mechanisms so that packages may be surreptitiously obtained from the package container.

further object of this invention is to construct a manually operated vendingr machine wherein slll'istantiallyv all of the primary operating elements o'l" the device have rotary movements.

.\.nother object of this invention is to construct a vending machine wherein the coin controlled mechanism and the delivery mechanism are rotary parts having a common axis. and an intermediate device for transmitting` certain forces from one mechanism to the other.

A still further object of this invention is to construct a vending machine includingr a rotative coin controlled mechanism. and a rotary delivery mechanism with a clutch member intermediate the coin controlled mechanism and the delivery mechanism.

still further object of this invention is to construct a manually operated vending machine including' a rotative coin carrier mounted upon a driving shaft and a rotative delivery mechanism mounted upon a driven sha tt. both of said shafts havinf: a common axis of rotation: and a clutch mechanism operatively connecting said shafts. said clutch mechanism beingr constructed to be operative during a certain portion of the rotationof the driving shaft and inoperative during` other portions of the rotation ot' theI said driving' shaft.

Still other and further objects of this invention will in part he obvious and will in part be pointed out hereinafter in the specitlcation following by reference to the accompanying' drawings wherein like parts are designated by like characters throughout the several igures thereof.

Figure l is a view showing a sectional elevation on substantially a vertical plane passing through the center line of the vendingr mechanism: the relationship of certain parts not directly within the section are indicated by dot and dash outlines. Fig. 2 is an extended perspective view looking from the operating handle rearwardly to the first delivery wheel and showingr the operating mechanisms separated to more clearly illustrate their operation and function. Figi'. is an extended perspective view of the operating mechanism looking from the delivery mechanism lock toward the operating handle. Fig, et is a front elevational view of the coin plate showing the outline of the front plate in dot and dash lines and illustrating only the operative parts between section lines A- and B-B. Fig. l. Fig. 3 is a detail view showing an elevation of the parts between the section lines B-B and (lC of Fig. 1. Fig. 6 is a view similar to Fig. 4 with the exception that the operating parts are illustrated in their position when a proper coin has been inserted in the machine and the operating lever' turned sufficiently for the coin to operate the locking mechanism to release the parts so that the machine may loe actuated to deliver ar package. Fife. 7 is a view similar to Fig. 5 with the exception that the parts are illustrated to correspond to the rotative position of parts in Fig. 6. fz'. e.. when the parts have heen rotated sufficiently to release the locking" mechanism so that the machine may be actuated to deliver a package. Fig. 8 is an elevational detail view illustrating substantiallv the mecl'lanisms hetween section lines (lr-C and D--D of Fig'. l. and showing the devices for unlocking or opening the packane receptacle to permit a package to be delivered. Fig'. 9 is a view illustrating the mechanism for closingV the coin slot when the supply of packages is exhausted from the package receptacle.

The drawings, and. the. specification together with the claims, all presented herewith, and constituting the present application, relate more especially to the coin control mechanism of my vending machine, the delivery mechanism being more fully illustrated, described and claimed in my companion application Serial No. 34,448 filed in the United States .Patent Oi'ice on the 16th day of June, 1915.

Vending machines are ainechanism adapted to be used by the general public and therefore are liable to abuse in operation, and must be constructed to guard against any possibility of rendering the mechanism opcrable by the introduction of strings, wires or improvised tools into the mechanism to release 0r unlock the same, and at the same time such machines must be so constructed as to insure operation, when a proper coin or token is inserted in the machine.

The mechanism illustrated in the accompanying drawings is constructed particularly with a view to strength, to withstand severe usage and abuse. And since rotative parts usually perform their function with a less degree of friction and wear than sliding or reciprocating elements, substantially all of the operative mechanism has been designed to include rotative parts. Since the function of the coin released devices is nominally that of a locking mechanism to which a predetermined coin constitutes the key, and since the delivery mechanism is entirely for the purpose of delivering a package after the release of the locking mechanisms, I have constructed the coin released mechanism as one group of devices and the delivery mechanism as another group of devices with a transmission or clutch intermediate the said devices; the clutch being so constructed that the delivery mechanism does not begin its effective operation until the coin released mechanism has been unlocked by a proper coin.

From the foregoing description it will be noted that the present device meets the requirements of strength, security, and insures effective operation when a proper coin is inserted.

Referring now to the drawings and more particularly to Figs. 1, 2 and 4, a driving shaft 1 is journaled in a front plate 2 and carries an operating handle 4 on its forward end, which may be secured in any convenient manner, as for example the pin 5. The inner side of the front plate 2 is provided with a circular recess in which is journaled the hub 6 of the circular coin plate 7. The front plate 2 is also provided with a recess to accommodate the coin plate 7, and the hub 6 of the said coin plate is of a length sufficient to provide a space between the coin plate 7 and the front plate 2, the depth of which space is slightly greater than the thickness of a predetermined coin. The front plate 2 is also provided with depressions constituting the coin insert chute 8 and a slug or improper coin exit 9. (See Fig. 4.) The coin plate 7 on its front surface near the upper edge thereof carries a pair of coin studs 10, the inner edges or sides of which are spaced apart a distance slightly less than the diameter of a predetermined coin, so that when the proper coin is dropped through the coin insert chute 8 it will rest upon and between the coin studs 10 with the upper edge of said coin slightly below the upper edge of the circular coin plate 7. A pair of segmental guards 11 are also mounted' on the front surface of the coin plate and may be retained in position thereon by means of securing devices such as rivets 12, and one end of each segmental guard is provided with a sharp cutting edge 14 which lies adjacent the edge of the coin plate 7, and as the coin plate is revolved in a manner to be hereinafter described, one of the cutting edges 14 will pass the lower edge or side of the coin insert chute 8, while the other cutting edge 14 will pass the upper edge of the improper coin exit 9. In each case a rotation of the coin plate 7 will cause the said cutting edges 14 to shear any string or wire introduced into the mechanism for the purpose of attempting to trip or unlock the coin released devices. Furthermore, the outer edges of the segmental guards 11 prevent coins reaching the operating mechanism of the device when it has been turned beyond the normal position of rest. A coin cam 15 comprising an irregular shaped member 16 is secured to the front plate 2 and is retained in the space between the front surface of the coin plate 7 and the front plate 2. This coin cam being secured to the front plate is therefore stationary and its outer surface is curved in such manner as t0 contact with the inner edge of a coin which may be retained between the coin studs 10, and when the coin plate 7 has been rotated sufficiently, the curve of the coin cam is such as to thrust outwardly the said coin from between the studs 10 into the outlet coin chute 16 which leads to the coin box 17.

Referring now to Figs. 1, 3 and 4, a collar 18 carrying a locking ratchet wheel 19 is secured to the driving shaft 1 by any desirable means, such as for example the pin 20, so that the locking ratchet wheel positively rotates with the power shaft 1 and the coin plate 7. A Y-shaped coin release lever 21 is pivotally mounted, for example on the bracket 22, in such manner that the locking pawl Q4 is between the limit teeth 25 and 26 on the ratchet wheel 19 and the coin contact roll 27 is forced against the outer edge of the segmental guard 11 by means of the coiled spring 28.

In order to normally maintain the operating handle 4 in a vertical position a centralizing mechanism is provided (Fig. 3)v

Which comprises a centralizing lever 29 pivotally mounted on a stud screw 30 that is .secured to the front plate 2. A contractile spring 31 normally retains the upper edge of the centralizing lever 29 in contact With the studs 32 and 34 that are set in the locking ratchet wheel 19. The stud 34 is considera-bly longer than the stud 32 for a reason which will be hereinafter explained. The centralizing lever 29 is provided with a depending portion on which is pivotally mounted an overthrow lever that is normally retained against a stop pin 36, by means of the spring 37, which is also carried by the centralizing lever 29. The upper end of the overthrow lever as at 38 is curved sufciently `to permit the short stud 32 to pass thereunder, While the long stud 34 will be engaged by the portion 38. By this mechanism it Will be seen that the contractile spring 31 will cause the centralizing lever 29 to rotate the coin plate `7 and the ratchet wheel 19 until the upper edge of the centralizing lever bears equally against the lower part of the studs 32 and 34 thus holding the operating handle 4 in a vertical position. The stud 34 Will engage With the portion 38 of the overthrow lever 35 as the operating handle 4 is rotated clockwise and the overthrow lever 35 Will be turned on its pivot to stretch the spring 37 so that if the handle 4 should be released With the pin 34 directly beneath the driving shaft 1, the extended spring 37 will contract thereby turning the overthrow lever and moving the stud 34 from beneath the direct vertical line including the axis of the power shaft and the axis of the stud 34, so that the parts will be thrown ofi' dead center and thel centralizing lever Will return the several parts to their normal position. Thus it Will be seen that the function of the devices just described is that of maintaining the coin controlled parts in normal position and o-bviating the possibility of the device stopping on dead center.7

The parts previously specied relate to the coin control elements which may be associated with various types of delivery mechanism, providing a suitable. transmission device is constructed intermediate the co-in controlled mechanisms and the delivery mechanism. In the present case the intermediate or transmission mechanism comprises a clutch including a collar 39 secured to the driving shaft 1 to constitute the hub on which a clutch arm 40 is fxedly secured. The clutch arm 40 carries a clutch pawl.41 which is maintained in engagement, by means o-f a spring 48, with a clutch disk 42 that is fixedly mounted upon the driven or delivery shaft 44. In the present case in order to obtain a secure and convenient bear- ,ies .fer the .gie shaft 44., l .have PrO- vided the inner end of the driving shaft 1 with a recess, such as at 45, and have also provided the delivery shaft 44 with a reduced portion or stud 46 Which is constructed to accurately fit the recess 45 thereby axially alining the driving shaft 1 with the driven shaft 44. The clutch disk 42 is provided with diametrically disposed notches 47 with which the end of the clutch pawl 41 is adapted to cooperate, due to the spring 48, to transmit poiver from the driving shaft to the driven shaft, whenI the driving shaft is rotated in a clockwise direction. In the type of delivery mechanism which I have herein illustrated, it is desirable that the delivery or driven shaft make but one-half revolution vvhile the power or driving shaft makes a complete revolution. Therefore, I have provided a release cam 49 comprising a stationary member secured to the front plate 2 and having its operative cam face 50 in the path of rotation of the outer end of the clutch pavvl 41. rEhe parts are so arranged that as the clutch arm 40 rotates, thereby carrying the clutch paivl into engagement with a notch 47, the said clutch pawl ivill be released from said notch by contact of the outer end 51 of the pawl with the operative cam face 50 of the releasing cam 49, when the delivery or driven shaft 44 has been rotated through substantially one-half revolution.

As it is desirable in vending machines to prevent the delivery mechanism being operated by insertion of devices through the exit chute through which the goods are delivered, I have provided a locking mechanism for securing the delivery devices in normal position. The specific locking mechanism herein illustrated comprises a delivery Wheel lock 52 pivotally mounted on a short shaft 54 that is supported in bosses which may be formed integral with the main casing 56. The delivery' Wheel lock includes a locking arm 57 provided with a notch adapted to enga ge one of the locking stop pins 58 which are carried by the forward delivery Wheel 59. Ar small spring GO normally urges the locking arm 57 toward the center of the delivery Wheel and a short cylinder 61 is pro vided on the delivery Wheel to prevent the locking arm from being moved beyond desired limits.v after the parts have been rotated beyond normal position. It is necessary that the delivery Wheel lock be released prior to the movement of the delivery or driven shaft, and therefore I have provided the clutch arm 4() with an offset G2 that coiperates with the release arm 64 vvhich is preferably formed integral With the delivery Wheel lock The type of delivery mechanism herein illustrated comprises a pair of delivery Wheels 59 and 65, both of Which have substantially the .n'egalar-reripliery and are in each case provided with a pair of eX- pulsion projections 66. Each delivery wheel is also provided with a substantially iiat portion 67 upon which a package, as for example X, to be delivered, may rest. Normally l prefer that' the bottom package may be supported upon L-shaped brackets 68 and also upon a hinged gate 69 that is controlled by means of a double S-shaped cam which is secured to the delivery or driven shaft 44. The hinged gate 69 is provided with an anti-friction roller 7l which coperates with the cam 70 in such manner as to permit the gate 69 to be dropped or opened when the delivery wheel is turned. This delivery mechanism is more fully described and shown in my companion application.

As it is desirable to prevent the insertion of coins when the magazine 72, indicated in dotted lines in Fig. l, is empty, I have provided a coin slot closure comprising a plate 74 slotted as at 75 to provide a guideway which cooperates with the stub screws 76 that are threaded into the bosses or posts 77, which I have in the present case formed integral with the upper part of the main casing 56. The plate 74 carries at its inner end a shoe 7 8 which, by means of the spring 79 is caused to lightly bear against packages' in the magazine holder and thereby maintain the notch 80 adjacent the coin insert chute 8. When the last package leaves the magazine it will be noted that the spring 79 will be free to contract and thereby move the plate 74 inwardly so that its outer end is substantially flush with the front plate 2 and so that the notch 80 is no longer adjacent the coin` chute 8, but a portion of the coin chute is obstructed by means of the outer end of the plate 74 thereby effectively closing the chute in such manner as to prevent the insertion of a coin.

The coin chute 8 previously referred to is of a width substantially the diameter of a proper predetermined coin so that it is impossible to introduce into the device a coin larger than is intended to be used in the machine thereby obviating the possibility of the mechanism being jammed by the coin resting on the studs l0 with the edge of the coin standing above the upper edge of the coin plate 7. If an improper coin of a diameter less than a predetermined coin be introduced into the machine it will fall between the studs 10, and taking the path indicated by the short arrows in Figs. 2 and 4, will pass out through the outlet chute 16 and be returned to the operator. lt will be noted that the operating handle 2 may at any time be turned a limited amount, z'. e., the distance between the limit teeth 25 and 26. This movement however, is not sufficient to actuate any of the/mechanisms other than the centralzing lever.

The movement is not suliicient to completely unlock the delivery wheels.

If a proper coin be introduced into the machine and the operating handle turned in a clockwise direction the coin will engage on its inner edge with the coin cam 15 and in passing beneath the coin contact roll 27 will force the roll outwardly (see Fig. 6)

Athereby removing the locking pawl 24 from the path of the limit tooth 26, (the other notches in the locking ratchet wheel 19 are one-way notches permitting the locking wheel to be turned in a clockwise direction but through the locking pawl 24 preventing 'turning in a counter-clockwise direction,)

and the operating handle may be turned one complete revolution. rlhe turning of the operating handle after the parts have been released will cause the delivery wheels to be unlocked and the clutch pawl to engage the clutch disk so that further movement will turn the delivery wheels. As the turning movement continues the driven shaft and the driving shaft rotate together thereby causing the S-shaped cam 70 to be turned suillciently to allow the outer end of the hinged gate 69 to drop so that the package X will rest upon the flat portion 67 of the delivery wheels. A further rotating movement will cause the expulsion projections 66 to engage the side of the package to eX- pel the same from the package magazine and thereby delivering the said package to the operator. A continued turning of the operating handle restores the coin plate 7 and the coin controlled mechanisms to normal position and permits the pawl 24 to drop between the limit teeth 25 and 26 of the locking ratchet wheel thereby locking the parts against operation until another proper coin is inserted. The construction is such that during the time when the space between the lower ends of the segmental guards 11 is passing beneath the coin contact roll 27, the pawl 24 is riding on the outer edge of the locking ratchet wheel, z'. e., on the end of one of the teeth in the said ratchet wheel thus preventing the said roll 27 from dropping into the specified space.

From the foregoing it will be noted that the desiderata reached by the present invention may be carried out in mechanisms comprising the equivalents of the various parts herein illustrated, which are depar- 1.111 a device of the character' described,
